OVERVIEW

The Plant Loop to Plant Loop Remote Interface (INPPR01)enables communication between a local and remote PlantLoop. Two modes (user-selectable) of control are available. Alocal Plant Loop is able to issue control commands and receiveException Report (XR) data from up to 32 remote Plant Loopswhen it is in the one-way mode. Only the local Plant Loop caninitiate control commands and request exception reports in theone-way mode. The two-way mode connects only two PlantLoops. In the two-way mode, either Plant Loop is able to initiatecontrol commands and request exception reports. Plant Loopto Plant Loop Remote Interfaces can connect through cable,modem or microwave link. Figure 1-1 shows a block diagram ofPlant Loop to Plant Loop Remote Interfaces in two-way control.The INPPR01 is a direct replacement of the Network 90 PlantLoop to Plant Loop Gateway (NPPG02).

HARDWARE DESCRIPTION

The Plant Loop to Plant Loop Remote Interface acts as anothernode on the Plant Loop. The interface consists of three moduleson a dedicated module bus.

Plant Loop to Plant Loop Transfer Module (INPPT01)

This module processes incoming and outgoing Plant Loop mes-sages, buffers data and communicates with other PPT modulesin remote Plant Loops. The PPT is a double circuit board mod-ule. It has a memory board and CPU board. The user selectsgeneral operating characteristics and point definitions throughsoftware configuration. Other characteristics such as type ofcontrol (one-way or two-way), Node ID and port options areuser-configured through dipswitches on the CPU board.

Bus Transfer Module (INBTM01)

The BTM is responsible for translating messages from the LIMand placing them on the module bus. It also receives messagesfrom the PPT. It translates those messages and sends them tothe LIM through a direct memory access (DMA) cable.

Loop Interface Module (INLIM03)

The LIM provides the communication link between the PlantLoop and the PPT. It receives messages from Plant Loop nodesand monitors loop status. The LIM forwards messages from theloop to the PPT (though the BTM) via a direct memory access(DMA) cable. Additionally, it receives messages from the PPT(through the BTM) and sends them to the proper node on theloop.

Additional Hardware

Some applications require additional hardware such as amodem network, radio link or microwave link. This hardware isnot part of the INPPR01 standard hardware. INFI 90 DigitalSlave Modules (IMDSO01 through IMDSO04, IMDSM05) sup-port control signals to these devices.

FEATURES

The Plant Loop to Plant Loop Remote Interface provides com-munication between a local loop and one or more remote loops.This interface has user selectable control modes. Selecting theone-way mode enables a local loop to receive exception reportsfrom up to 32 remote loops. In the one-way mode, only thelocal loop can initiate control commands. The two-way modeenables bidirectional control and exception reporting between

INTRODUCTION

This section explains the operation of the Plant Loop to PlantLoop Remote Interface.

LOCAL/REMOTE COMMUNICATIONS

Local and remote PPTs communicate with each other througha series of commands and replies over the serial ports. In theone-way mode, the local PPT issues commands only; intwo-way, both the local and remote PPTs issue commands. Thecommand format is:

where:

1. Loop number is the loop that responds to the command (1byte field).

2. Message byte count is the total length of the message (2byte field).

3. Command code is the command code the PPT processes (1byte field).

4. Command data is the specific command (variable lengthfield).

5. Checksum is the sum of all the bytes in the command (1byte field) or CRC, the cyclic redundancy check word computedfor all of the bytes in the command using the CRC-16 algo-rithm (2 byte field).

All communications between interfaces use this format.INPPR01 commands are a modified form of Plant Loop to Com-puter Interface commands (refer to I-E93-905-9 for commanddetails). The PPT format eliminates the key field from the PCIcommand. In addition to PCI commands, the PPT processes acommand (code 29) that permits passage of a required PPTmessage.

DESCRIPTION AND OPERATION ®

DATA INTEGRITY

Verification of data integrity consists of even parity checkingand the checksum in each command and reply format. Theinterface retries a transaction whenever it detects a communi-cation error.

There are two levels of communication breakdown detection.The first level detects a complete failure of the communicationlink. Should this occur, Function Code 130 output block onewill be set (logic one) and the alarm status bit set if port 1 fails.If port 0 fails, the output of block two will be set (logic one) andthe alarm status bit set.

The second level of communication failure concerns the loss ofa single remote interface. If this occurs, all blocks coming fromthat remote interface are bad quality. The PPR makes use of auser-configurable watchdog timer or absolute retry count indetermining the sensitivity to these failures (refer toI-E93-200-20 for information about Function Code 130, S10and S12).

TIMING INTERVAL

The local interface attempts communication twice a secondwith all the remote interfaces. Each successful transactionresets the communication watchdog timer. Therefore, if thecommunication link is faulty, no transactions occur success-fully. After the watchdog time period expires, the link ismarked bad.

For all communication transactions, the watchdog timer isreset on the reception of each character. If the time intervalbetween characters in a transaction exceeds 1.25 seconds, thetransaction is flushed and the remote interface is marked asbeing suspect. This condition causes retry logic to begin. Retrylogic consists of retrying communication once per second for anumber of times equal to one-fourth the watchdog time periodif the absolute retry count is set to zero. A non-zero absoluteretry count causes a specific number of retries (the number ofthe retry count). If the failure persists after the retry periodexpires, the remote interface is internally marked off-line andthe quality of all the points it provides are marked bad.

Thereafter, a single retry of the failed remote interface occursat a period equal to one half the watchdog timer period until asuccessful transaction occurs. The local interface sets thequality of all the points to their original state (before the com-munication failure). It also does a one time poll of the currentvalue of each point.

A user-configurable time delay envelopes each command/replysequence. This time delay accommodates the keying up/down

DATA INTEGRITY

DESCRIPTION AND OPERATION

of modems and transmission equipment. The interface coordi-nates this activity through the RTS (Request-To-Send) signal ofthe RS-232-C port for modems or through digital outputs whenusing Digital Slave Modules (IMDSM05, IMDSO01/02/03/04)to enable other transmission equipment.

Transmit/Receive Timing

The user can set up the RS-232-C ports to operate as Data Cir-cuit-Terminating Equipment (DCE) or Data Terminal Equip-ment (DTE). In the DCE mode, the Request-To-Send (RTS) lineis always asserted. In the DTE mode, the RTS line is assertedbefore data transmission and inhibited after data transmissionoccurs.

The following events occur (see Figure 2-1) on port 0 whentransmitting a command:

1. Assert RTS on the RS-232-C port (DTE mode) or set digitaloutputs 1 and 4 on the digital slave module.

2. A delay occurs between the time the port 0 asserts the RTS(or the digital outputs are set) and the command transmissionoccurs. Function Code 130 (S5) sets this delay (inmilliseconds).

3. Output 4 is reset.

4. A delay occurs between the time output 4 is reset and out-put 1 is reset. Function Code 130 (S6) sets the length of thisdelay.

5. Output 1 is reset and RS-232-C RTS signal is inhibited(DTE mode).

6. A delay set by S5 of Function Code 130 occur between theoutput 1 reset and the reception of the reply.

7. The remote target issues a reply.

The following events occur (see Figure 2-1) when Port 0receives a command:

1. The port receives the command.

2. A time delay set by S6 of Function Code 130 occurs.

3. The RS-232-C asserts the RTS signal (DTE mode) or setoutputs 1 and 4 on the digital slave modules.

INTRODUCTION

This section explains special handling procedures, switch set-tings for each interface module, and how to install relatedhardware. Complete the preliminary procedures in this sectionbefore placing the INPPR01 into operation.

SPECIAL HANDLING

Plant Loop to Plant Loop Interface modules use ElectrostaticSensitive (ESD) devices. Follow these handling procedures:

NOTE: Always use the Bailey Field Static Kit (P/N 1948385A1)when working with interface modules. This kit connects the staticdissipative work surface and technician to the same ground point.

1. Keep the modules in their special anti-static bags until youare ready to install them in the system. Save the bags forfuture use.

2. Ground the anti-static bag before opening.

3. Verify that all devices connected to the modules are prop-erly grounded before using them.

4. Avoid touching the circuitry when handling the module.

UNPACKING AND INSPECTION

1. Examine the PPT, LIM and BTM immediately to verify thatthey have not been damaged in transit.

2. Notify the nearest Bailey Controls Sales Office of any suchdamage.

3. File a claim for any damage with the transportation com-pany that handled the shipment.

4. Use the original packing material and/or container to storethe modules.

5. Store the module in an environment of good air quality andfree from temperature and moisture extremes.

TERMINATION UNIT (MODULE) CONFIGURATION

Two of the interface modules (INLIM03, INPPT01) require ter-mination. The INPPT01 terminates with the NTMF01 orNIMF01/NIMF02. The INLIM03 terminates with the NTCL01 orNICL01. Appendices A through D contain disphunt configura-tion information. Figure 3-4 shows a diagram of the NTMF01and NTCL01 in a redundant installation. Figure 3-5 shows adiagram of the NIMF01/NIMF02 and NICL01 in a redundantinstallation.

NTMF01/NIMF01/NIMF02 Configuration

The TMF and IMF provide the INPPT01 with two RS-232-Cports. Configure these ports to operate as DTE, DCE or diag-nostic terminal. Refer to Figures A-1, A-2, and A-3 for NTMF01dipshunt configurations. Refer to Figures C-1, C-2, and C-3 forNIMF01/NIMF02 dipshunt configurations.

NOTE: You must use the NIMF01 and NIMF02 when using termina-tion modules to terminate a redundant interface. Non-redundantinterfaces need only the NIMF01.

ONE-WAY CONTROL

Configure port 0 on the local and remote interfaces to act asDTE. One local INPPR01 can communicate with up to 32remote interfaces in the one-way control mode. Additionalcommunication equipment such as a modem network, radiolink or microwave link is required when interfacing multipleremotes. The user supplies any additional equipment that isneeded.

INSTALLATION ®

When directly connecting only one remote interface in one-waycontrol, set port 0 on the local interface to act as a DTE. Setport 0 on the remote interface to act as DCE.

NOTE: Always configure port 1 as a utility port if it is not used as aninterface communication port. The PPT option switch (U72) position4 must be set to 0 (utility option). Port 1 will always act as a DCE inthis configuration.

TWO-WAY CONTROL

The interface requires both serial communication ports in thetwo-way control mode. Connect port 0 of the local Plant Loop toport 0 of the remote Plant Loop. Connect port 1 of local PlantLoop to port 1 of the remote Plant Loop.

Configure the termination unit to act as DTE to enable thePlant Loop to Plant Loop Transfer Module to communicate withDCE (i.e, a modem). Configure the termination unit to act asDCE to enable the PPT to communicate with DTE (i.e., a termi-nal). Figure A-4 shows how the termination dipshunt configu-ration directs the RS-232-C signals.

NTCL01/NICL01 Configuration

The TCL and ICL provide the INLIM03 with Plant Loop termina-tion. The user has the option of using Twinax or Coax cable toconnect the interface to the Plant Loop. Tables B-3 (NTCL01)and D-3 (NICL01) show the jumper settings for twinax andcoax cables. Set the jumpers accordingly for your application.

NOTE: For complete cable and TU/TM installation information, referto the Termination Unit Manual l (I-E93-911).

INSTALLING THE INTERFACE MODULES

If the switch settings on the interface modules are complete,they are ready to be installed in the Module Mounting Unit(MMU).

Installing the INPPT01

WARNING Disconnect power before installing dipshunts for slave mod-ules on the MMU backplane (slave expander bus). Failure to doso could result in severe or fatal shock.

3 - 10 I-E96-624A

INSTALLATION

I-E96-624A

To install the PPT:

1. Verify the PPT slot assignment in the MMU.

a. If you are installing redundant PPTs, install a 24 pindisphunt in the Slave Expander Bus socket between theslot used by the primary PPT and the slot used by the sec-ondary PPT. Both PPTs must reside on the same SlaveExpander Bus.

b. Each PPT must reside on its own module bus.

2. Attach the hooded end of the cable (NTKU01 for theNTMF01; NKTM01 for the NIMF01 and NIMF02) to the MMUbackplane cable connector opening for the PPT. The other endof the cable attaches to the termination unit or backplane ofthe Termination Mounting Unit (NTMU01).

3. Guide the top and bottom edges of the circuit card alongthe top and bottom rails of MMU.

4. Slide the module into the slot; push the module until thefront panel is flush with the top and bottom of the MMU frame.

5. Turn the two captive latches a half turn to lock the modulein place.

Installing the INLIM03 and INBTM01

The LIM and BTM should be installed as a pair in adjacentslots. To install the LIM/BTM:

1. Verify the MMU slot assignments for the modules. If youare installing redundant LIM/BTM pairs, each BTM must beinstalled on the module bus that belongs to its related PPT.

2. Attach the hooded end of the cable (NKLS03 for NTCL01;NKLS04 for the NICL01) to the MMU backplane cable connec-tor opening for the LIM. The other end of the cable attaches tothe termination unit or TMU backplane.

3. Connect one end of the Bailey supplied ribbon cable (DMAcable) to the P4 connector on the LIM. Connect the other end ofthe DMA cable to the P4 connector on the BTM (see Figures 3-2and 3-3).

4. Guide the top and bottom edges of both circuit cards alongthe top and bottom rails of adjacent slots in the MMU.

5. Slide the modules into the slot; push the module until thefront panels are flush with the top and bottom of the MMUframe.

6. Turn the two captive latches a half turn to lock the modulein place.

INSTALLING A REDUNDANT INTERFACE

Installing a redundant interface requires an additional set ofINPPT01, INLIM03 and INBTM01 modules. Both PPT modulesmust be on the same Slave Expander Bus, but reside on sepa-rate Module Bus. Each PPT has a pair of LIM/BTM modules ona dedicated Module Bus.

Observe the following conditions when installing a redundantinterface:

1. U72 position 8 must be set to 0 on the primary PPT.

2. U72 position 8 must be set to 1 on the secondary PPT.

3. SW1 all positions must be set to 0 on both BTMs.

4. The slave expander bus of two adjacent MMUs (one on topof the other) are connected with the expander bus extendercable (Bailey P/N 1958502A0340).

5. The module bus between these MMUs are not connected.

Applications that use redundant communication equipmentmay require additional hardware. Figure 3-6 shows a diagramof the interface using the IMDSM05 to enable redundant trans-ceivers. Function Code 130 provides the software the PPTneeds to enable the transceivers. Voltage levels and polaritiesof enable signals to transceivers and other communicationequipment may vary. Refer to the applicable user manual whenconnecting this equipment to the IMDSM05, IMDSO01/02/03/04 Digital Slave Module.

INTERFACE CONFIGURATION

The user must configure the PPT with the proper functioncodes before it can be placed into service. The PPT configura-tion determines interface operating characteristics such astime synchronization, serial communication rate, node defini-tion, point definitions and general execution characteristics.

Table 3-9 lists the function codes used by the INPPR01. Referto the Function Code Application Manual (I-E93-900-20) forinformation about the function codes in Table 3-9.

2. Recovery from an operator-initiated stop or a moduletimeout.

LOOP INTERFACE MODULE LEDs

There are eight LEDs on the LIM faceplate (see Figure 4-2).These LEDs display the contents of event and error counters,and pass/fail information when on-board diagnostics are run(refer to Tables 3-4 and 3-5 for a list of event and error countercodes).

BUS TRANSFER MODULE LED

The Bus Transfer Module has one red/green LED that displaysthe module's operating condition (see Figure 4-3). The BTMStatus LED has three possible states. Refer to Table 4-2 forBTM Status LED states and their meaning. Section 5 explainsthe corrective action to take if the Status LED displays a BTMhardware failure.

MODES OF OPERATION

The Plant Loop-to-Plant Loop Remote Interface has threemodes of operation: Configure, Execute and Error. Within theExecute mode the module has two methods of control: one-wayor two-way control.

Configure Mode

This mode applies to the INPPT01 module. Module configura-tion requires an INFI 90 operator interface device (i.e., Opera-tor Interface Station, Management Command System,Engineering Work Station, etc.). Refer to Section 3 and to theinstruction for your operator interface device for informationabout interface configuration.

Execute Mode

This is the normal mode of operation for the PPR. In the exe-cute mode, the PPR issues requests for exception reports (XRs)twice a second, collects XRs, exercises control (local to remote),allows the operator to adjust tunable module specificationsand configure modules in remote loops. The interface entersone of the two control types that the user configures duringinstallation.

MODES OF OPERATION

I-E96-624A

Error Mode

The PPT enters this mode if the built-in system diagnosticsdetect a hardware or configuration error. If the PPT detects ahardware error, the module halts and displays an error code onthe CPU LEDs. If the CPU LEDs display a configuration error,the module remains in the error mode. Refer to Section 5 forcorrective action when the PPT enters the error mode.

One-Way Control

The PPT option switch setting (set during installation) deter-mines if the module is in one-way control. In one-way control,the local Plant Loop requests XRs from all remotes twice a sec-ond. The operator does module tuning and configuration, andissues control commands to the remote Plant Loops throughthe operator interface.

This type of control requires only one serial port (port 0). Port 1can also be used as an additional link through which the localloop issues commands. Using both ports increases the totalthroughput of the PPT (see Figure 4-4).

Two-Way Control

In two-way control, bidirectional communication requires bothports on both Plant Loops (Port 0 to Port 0; Port 1 to Port 1).Both loop interfaces can issue requests, control commandsand do module tuning and configuration. The local interfaceuses one serial port to issue commands and receive replies (seeFigure 4-5). The remote interface uses the other port for thesame purpose. As in one-way control, the PPT requests XRstwice a second; control and configuration commands arethrough operator action.

REDUNDANT INTERFACE OPERATION

Redundant interface configurations require two sets of LIM/BTM and PPT modules. Each set of modules reside on a sepa-rate module bus. Redundant interfaces share a common slaveexpander bus. Upon start-up, one interface assumes the pri-mary role; the other waits in a backup role. The primary PPT

downloads the interface configuration to the secondary (redun-dant modules are identically configured to their primary coun-terpart). If the primary interface fails, the redundant unit takesover and re-establishes the point data.

INTERFACE POINT CAPACITY

There are three factors that determine the maximum numberof points in a PPT configuration. Those factors are: point type(exception report data type), the number of devices that receiveinterface generated exception reports and the total memoryavailable (440,000 bytes). Table 4-3 lists the required memorybytes for all point types when memory usage is for:

1. The local PPT receiving points from the remote PPT.

2. The remote PPT (in two-way mode) receiving points fromthe local PPT.

Table 4-4 lists the required memory bytes for all point typeswhen the memory usage is for:

1. The remote PPT sending points to the local PPT.

2. The local PPT (in two-way mode) sending points to theremote PPT.

NOTE: The PPT has a capacity of 5,000 blocks.

MEMORY USAGE EXAMPLE

In this example, a pair of interfaces in one-way mode has thefollowing mix of points in their configuration:

500 digital points (S3 of FC131 = 0)200 analog points (S3 of FC131 = 1)50 stations (S3 of FC131 = 2)

Distribution of 750 total points on the remote loop is among 20modules residing in 10 different PCUs. There are five OISs onthe local loop. Each OIS receives all of the points.

Memory Usage in the Local PPT

The points are coming to the local from the remote, therefore,Table 4-3 applies. The calculations are:

500 digital points x 16 bytes/point = 8,000 bytes200 analog points x 30 bytes/point = 6,000 bytes50 station points x 76 bytes/point = 3,800 bytes

Each OIS receives all 750 points:5 OIS x 750 points x 6 bytes/point = 22,500 bytesTotal memory used in the local PPT = 40,300 bytes

Memory Usage in the Remote PPT

These points are to be sent to the local, therefore, Table 4-4applies. The calculations are:

500 digital points x 18 bytes/point = 9,000 bytes200 analog points x 22 bytes/point = 4,400 bytes50 station points x 70 bytes/point = 3,500 bytes20 modules x 10 bytes/module = 200 bytes10 PCUs x 16 bytes/PCU = 160 bytesTotal memory used in the remote PPT = 17,260 bytes

SECURITY FUNCTIONS

The PPT performs both hardware and software security checksto insure module integrity.

Hardware Checks

The PPT does the following hardware checks:

1. Error Detection and Correction - Detects single bit anddouble bit errors in the dynamic RAM. Corrects single biterrors; halts PPT operation on double bit errors.

2. Illegal Address Detection - Detecting an illegal address gen-erates a bus error and the PPT halts operation.

3. Machine Fault Timer - The microprocessor updates thistimer. A machine fault timeout halts module operation.

Software Checks

The PPT does the following software checks:

1. Module Diagnostics - Module diagnostics execute automat-ically on system power up. PPT faceplate LEDs display errorconditions if the diagnostic tests fail.

2. Module Status Check - This test verifies checksums of theUVROM and NVM. Discrepancies cause the PPT Status LED toflash green and PPT operation halts.

Utilities

The utilities menu shown in Figure 4-6 is available to the userby attaching a diagnostic monitor to serial port 1. Items 1, 4and 5 are used for Bailey Engineering purposes. Items 2 and 3are available to the user.

APPENDIX C - TERMINATION MODULECONFIGURATION (NIMF01/NIMF02)

I-E96-624A

INTRODUCTION

The INPPT01 can use the NIMF01 for termination. The NIMF02is required when terminating redundant interfaces. The disp-shunt configurations shown in Figure C-1 through C-4 applyto the NIMF01 and NIMF02. Figure C-1 shows the dipshuntconfiguration required when connecting a local and remotePPT (DTE) via a modem (DCE). Figure C-2 and C-3 show thedipshunt configuration required when directly connecting alocal PPT (DTE) to a remote PPT (DCE) via a cable.

I-E96-624A

INTRODUCTION

The INLIM03 can use the NICL01 for termination. Table D-1lists the terminal assignments for the loop input/output con-nections. Table D-2 provides jumper settings associated withcable type. Figure D-1 shows twinax cable connections forNICL01.

NOTE: Twinax cables connect to the terminals. Coax cables con-nect to the BNC connectors.

CAUTION Ensure that the end marked J1 is connected to P1 on theNICL01, and J2 is connected to the LIM. Failure to do so couldresult in module damage (see Figure D-1).

ATTENTION S'assuree que L'extremite identifiee par J1 est reliee a P1 dumodule NICL01 et que J2 est reliee au module LIM. Sinon, lesmodules pouiraient etre endommages (voir la figure D-1).
